Description

  The present invention relates to a bedding having a multilayer structure used as a skin comforter, a floor pad or a bed pad. The bedding of the present invention is particularly suitable for use in summer.

  The performance required for the bedding for summer is greatly different from the performance most important for the bedding for winter, that is, heat retention, and it is not hot and does not get steamed even when sweating.

  Examples of inventions related to bedding for summer use are those in which a thin lace fabric is superimposed on a towel fabric, and a gauze fabric is superimposed on the surface of the towel fabric with a batting layer interposed therebetween, and a lace fabric is formed thereon. There are a superposed one (see Patent Document 1 above) and a high degreased, additive-free cotton gauze that is overlaid and sewn together (see Patent Document 2).

  By the way, hemp has been conventionally used in summer clothes and sheets. This is because hemp fabric has a light touch and has the highest thermal conductivity among ordinary fibers, and therefore has a large ability to transmit body heat to the outside through the fibers. Furthermore, since hemp is excellent in moisture absorption or sweat absorption and moisture release or wicking, if hemp fabric is used, it will not be steamed even if there is sweat.

  Therefore, in order to satisfy the performance required for summer bedding, it can be said that hemp fabric should be used as the side fabric. However, unlike sheets and bedding covers, in the case of bedding, the above-mentioned required performance is not always satisfied only by using hemp as a side fabric. In order to increase the degree of satisfaction of the required performance, it is necessary to devise the filling material such as cotton and the structure of the bedding itself.

  If the bedding of the present invention is used, it is freed from sleepiness in summer.

  Hereinafter, preferred examples of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a cross-sectional view showing an example of the layer structure of a bed pad 100 of the present invention. The bed pad 100 includes a front surface layer 1, a back surface layer 3, and two inner layers 5 and 7 located between the front surface layer 1 and the back surface layer 3.

  In FIG. 1, the layers are in contact with each other, but the layers do not have to be in complete contact with each other, and there may be a space between the layers. For example, there is a space between the surface layer 1 and the inner layer 5, and the back surface layer 3 and the inner layer 7 as in the example described in FIG. 4, which is a cross-sectional view showing an example of the outer peripheral portion of the bedding of the present invention. Also good.

  Both the surface layer 1 and the back surface layer 3 are made of woven fabric or knitted fabric. Moreover, at least one of these contains 25% or more of hemp. The inner layers 5 and 7 are either woven fabric, non-woven fabric or knitted fabric, or one of the layers in contact with the fabric containing 25% or more of hemp is either woven fabric, non-woven fabric or knitted fabric. The other is a material other than woven fabric, non-woven fabric and knitted fabric. That is, the combination of the materials of each layer in the bed pad 100 having the four-layer structure of the present invention is as shown in Table 1. In addition, although the name and code | symbol are attached | subjected in this way about the surface layer 1 and the back surface layer 3 for convenience of explanation, the surface layer and the back surface layer may be interchanged.

  In the bedding of the present invention, the woven or knitted fabric used for at least one of the front surface layer 1 and the back surface layer 3 contains 25% or more of hemp. Both the surface layer 1 and the back layer 3 are preferably woven or knitted fabrics containing 25% or more of hemp. The reason why the hemp content is 25% or more is to make use of the properties of hemp, that is, the property of transferring body heat to the outside, moisture absorption or sweat absorption, moisture release or divergence. The hemp content is preferably 30% or more, more preferably 50% or more, still more preferably 80% or more, and most preferably 100%. As the hemp, either ramie or linen can be used.

  “A woven or knitted fabric containing 25% or more of hemp” used for either or both of the surface layer 1 and the back layer 3 is said to contain not only woven or knitted fabric of 100% of hemp but also 25% or more of hemp. Under the conditions, a woven fabric or a knitted fabric using two or more kinds of fibers including hemp is also included. In such “use of two or more types of fibers”, a mixed yarn obtained by spinning two or more types of fibers in a woven fabric or a knitted fabric is used, and yarns made of different fibers are used for warp and weft. (Knitting), knitting using two or more different fiber yarns (knitting), and the like are included. Other fibers used with hemp when not 100% hemp are not particularly limited, but examples include cotton, rayon, polyester and nylon.

  At least one of the surface layer 1 and the back surface layer 3 is preferably made of woven fabric, and more preferably both are made of woven fabric. Further, as the woven fabric, a gauze fabric is particularly preferable. “Gauze fabric” means 20 to 40 yarns to be used, and the number of yarns to be driven is untwisted or sweet twisted yarn with 25 to 50 warps per inch and 25 to 50 wefts per inch. A coarsely woven plain weave. Moreover, as a material fiber of a gauze fabric, hemp and cotton are preferable.

  The “woven fabric, non-woven fabric and knitted fabric” used for the inner layer includes all woven fabric (fabric), non-woven fabric and knitted fabric manufactured using various fibers. The weaving method (for woven fabric), the production method (for non-woven fabric), and the knitting method (for knitted fabric) are not particularly limited. The “various fibers” include all fibers, that is, natural fibers, semi-synthetic fibers, regenerated fibers, synthetic fibers and the like. The fiber used for the manufacture of the woven fabric, the nonwoven fabric, and the knitted fabric and the yarn formed by spinning the fiber may be used alone or in combination of two or more. Here, “two or more types” means that, for example, in a woven fabric or a knitted fabric, a mixed yarn obtained by spinning two or more types of fibers is used, and yarns made of different fibers are used for warp and weft. (Knitting), knitting using two or more different fiber yarns (knitting), manufacturing a non-woven fabric using two or more fibers, and the like.

  Examples of the weaving method for manufacturing the woven fabric include plain weave and twill weave. Examples of the nonwoven fabric include chemical bond, thermal bond, air laid, spun bond, melt blow, spun lace, needle punch, and stitch bond. Moreover, what processed various processing to the nonwoven fabric, for example, what coated the chemical | medical agent and resin, and the composite nonwoven fabric which combined the nonwoven fabric and the other raw material can also be used. Examples of the method of knitting in manufacturing the knitted fabric include raglan knitting, warp knitting, circular knitting, and flat knitting.

  The material fibers used for the production of “woven fabric, non-woven fabric and knitted fabric” are not particularly limited, but examples thereof include chemical fibers such as polyester, nylon and acrylic, natural fibers such as cotton, hemp, silk and wool, Examples thereof include recycled fibers such as rayon. As the material fiber, it is preferable to use at least one selected from the group consisting of cotton, ramie, linen and rayon, which is excellent in body heat transfer.

  Especially in the case of bedding for summer, the combination of material fibers and weaving method (for woven fabric), manufacturing method (for non-woven fabric) or knitting method (for knitted fabric) provides excellent breathability. It is preferred to select and use them. An example of a material excellent in air permeability is a gauze fabric, and a gauze fabric of hemp or cotton is particularly preferable.

  Of the two or more inner layers, at least one layer that is in contact with the layer containing 25% or more of hemp is a woven fabric, a nonwoven fabric or a knitted fabric, but the other inner layers are not limited to materials. That is, “materials other than woven fabric, non-woven fabric and knitted fabric” can also be used. The “material other than woven fabric, non-woven fabric and knitted fabric” used for the inner layer includes all materials used as bedding materials other than woven fabric, non-woven fabric and knitted fabric. Specific examples include cotton, bread, felt, urethane / sponge or rubber, urethane processed products, and the like. The material of cotton and bread is, for example, cotton, kapok, wool, and various chemical fibers such as polyester, acrylic, and polypropylene. The felt material is natural hair such as wool or acrylic. Urethane sponge or rubber is a layered material made of polyurethane. Urethane processed products are those obtained by impregnating and solidifying a polyurethane solution or emulsion on a base fabric (urethane impregnated product), or by applying and drying a polyurethane solution or emulsion on the base fabric (urethane coating) Processed product).

  Cotton, bread, felt, urethane sponge or rubber, urethane processed products, etc. are useful for imparting cushioning properties to bedding. Therefore, it is often used in bedclothes such as bed pads and bed pads. In addition, when “materials other than woven fabric, non-woven fabric and knitted fabric” are used for the inner layer, in general, in order not to disturb as much as possible the breathability, moisture absorption or sweat absorption, moisture release or divergence of the bedding of the present invention. Used in small amounts (ie, in a small thickness state). Or what was processed so that air permeability may be maintained is used. In the present invention, “materials other than woven fabric, non-woven fabric and knitted fabric” are used in the present invention for the inner layer in contact with the woven fabric or knitted fabric layer containing at least 25% of hemp at least one of the front surface layer and the back surface layer. do not do. This is because the hemp-containing layer is used as a side in contact with the human body when the bedding is used to dissipate body heat.

  As the bedding of the present invention, it is preferable that all the inner layers are any one of a woven fabric, a nonwoven fabric and a knitted fabric. That is, among those shown in Table 1, those of Examples A and C are preferable. In the case of Example C, the back surface layer 3 is preferably a woven or knitted fabric having at least one material selected from the group consisting of hemp (linen, ramie), cotton and rayon as a material fiber (provided that Hemp content is less than 25%).

  In the bedding of the present invention, when a non-woven fabric is used for the inner layer, a functional non-woven fabric such as a multi-hole non-woven fabric with good air permeability, an improved water-absorbing dispersibility, or an anti-bacterial deodorant / tick-proof property is used. It is preferable to use it. The “multi-hole nonwoven fabric” is a nonwoven fabric in which holes such as woven fabric are regularly formed, for example, a spunlace nonwoven fabric.

  Although FIG. 1 and Table 1 show an example in which the inner layer is two layers, the inner layer only needs to be two or more, and the number is not limited. The number of inner layers is usually 2 to 5, preferably 2 to 4, and particularly preferably 2 or 3. What is necessary is just to select the number of layers, the material which comprises each inner layer, and a material so that the required performance for every use of a bedding (for example, a use such as a bedding or a bed pad) may be satisfied.

  As for the bedding of this invention, the surface layer and the back surface layer are couple | bonded directly or indirectly in the outer peripheral part at least. “The front surface layer and the back surface layer are directly bonded at the outer peripheral portion” means, for example, that the outer peripheral portion of the front surface layer and the back surface layer is sewn and the front surface layer and the back surface layer are integrated, and the inner layer is the front surface It refers to an aspect that is filled between the layer and the back surface layer, and “the surface layer and the back surface layer are indirectly bonded at the outer periphery” means, for example, between the surface layer and the back surface layer. In this state, the outer peripheral part is integrally sewn in a state where all or part of the inner layer exists. Further, since “at least at the outer peripheral portion”, portions other than the outer peripheral portion may be joined by sewing or the like. It is preferable that all the layers are sewn together in the outer peripheral portion.

  FIG. 2 is a cross-sectional view showing an example of the outer peripheral portion of the bedding of the present invention. On the outer periphery of the bedding, there are separate fabrics 20 that wrap around the cut-off ends of the surface layer 1, the inner layer 5, the inner layer 7, and the back surface layer 3, and these four layers and the four layers derived from the separate fabric 20 (surface Two layers of the folded back fabric 20 are present on the layer 1 and two layers of the folded back fabric 20 are present under the back surface layer 3). . The end treatment shown in FIG. 2 is referred to as “hem winding”. This is an example of “the front surface layer and the back surface layer are indirectly coupled at the outer peripheral portion”.

  As another example of “the surface layer and the back layer are indirectly bonded at the outer periphery”, as shown in FIG. 3, the inner layer 5 is located between the surface layer 1 and the back layer 3 at the outer periphery. Although the inner layer 7 does not exist between the surface layer 1 and the back surface layer 3, the surface layer 1, the inner layer 5, and the back surface layer 3 are sewn. On the other hand, in the example of “the front surface layer and the back surface layer are directly bonded at the outer peripheral portion”, as shown in FIG. 4, the inner layers 5 and 7 do not exist in the outer peripheral portion. Only those that are sewn.

  The method of not exposing the cut ends of the surface layer 1, the inner layer 5, the inner layer 7 and the back surface layer 3 is not limited to these. For example, the surface layer 1 and the inner layer 5 and the inner layer 7 and the back surface layer 3 each have one unit. It may be a bag sewing.

It is preferable that each layer of the bedding of the present invention is sewn and integrated at a portion other than the outer peripheral portion. FIG. 5 is a plan view showing an example of a summer skin comforter 200 of the present invention. In this example,
Even at locations other than the outer peripheral portion, all the layers are integrally sewn with the thread 40, that is, quilted. In this way, the inner layer will not be displaced or swung.

  Hereinafter, the bedding of the present invention will be described more specifically with reference to examples.
